IMPRovjsMENT IN SELF-SUPPORTING FENCE.

I The Schedule referred to/,in these Letters Patent and making part ofthe same To all whom it may concern:

Bei it known that I, THOMAS FLINN, of Birmingham, in the county ofOakland, and the State of Michigan, have invented a new and usefulImprovement in Portable Felices; and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, and to the letters of reference markedthereon.

Figure `1 represents alwrspectire view of a section of a fence, as Ipropose to construct it;

Figure 2 is a portion of the cap, showing the angular lapjoint Figure 3is a vertical section, on line a: x of tig. 4;

Figure 4 is a front elevation and Figure 5 isa bottom view ofthe posts,showing their tenons and the position of the shoulders with ret'erenceto each other.

The same letters indicate the same' parts inthe several lignres. r

l\l y inreution relates'to portable felices, which are constructed insect-ions; aml

My improvement consists in the atta-r-lnnent of the posts which supportthe bars ofthe fence to the basepla-tes, by which all nailing isavoided.

A, in the drawings, represents a. hase-plate of a fem-e, which is to bemade `of suitable dimensions, so as to give a tirm support. totheupright portions ofthe felice. A mortise'is to be cnt in the centre ofthe plate for'the reception ofthe tenons ot' the posts, to he. ot' thelsinne. width as the. tenons, its length being such, that when the postshaue been inserted, a space is left at one. end tor the receptionl of akey.

B B' represent the double posts ota fence, between which the bars areconlined. Tenons are to be formed at their lower ends, fitting into themortises in their base-plate, to which they are secured by the wedge band key b'. The position of the posts wit-h reference to each other issuch, that the shoulder formed on the post B stands on the base in linewith the mortise, while the shoulder on the right angle to the same.

C C represent the bars, the ends of which, in each section of fence, areto be formed as shown in lig. 4, so as to make a lap-joint. with theadjoining section. They-are to be secured between the d onble posts inany convenient unlnner.

D represents the cap, to which the top ends of the posts are firmlysecured. The formation of the ends where the sections join is clearlyshown in figf2.'

By the above-described construction and arrangement ot' the parts, afence produced which may be readily taken apart and transported from oneplace to another, and which, when properly put up, combines strength anda neat appearance.

' Havhn,lr thus described my invention,

.Vhat I claim, and desire to secure by Letters Patent, isy The.combination of the base A, posts B, keys b', bars C, and cap D, allconstructed and arranged substantially as shown and described.

In testimony whereof, I have signed my name to thi; specification, inthepresence of two subscribing witnesses. l

THOS. FLINN.
